AI Nuclear Theme Stocks Surge to Mid-1 Trillion Won Market Cap Today

Next-generation U.S. nuclear startup Oklo Inc. (NASDAQ: OKLO) jumped 9.25% on April 15, closing at $64.11 on the New York Stock Exchange.

Its market capitalization swelled to about $11.1 billion (roughly KRW 15 trillion), adding some $1.1 billion (around KRW 1.5 trillion) in a single day, while trading volume topped 12.2 million shares as short-term flows poured in.

Recently, Wedbush lowered its price target from $150 to $110 but kept an Outperform rating. Oklo has attracted short-term traders on the strength of its roughly 14 GW power-supply pipeline—including projects for AI data centers—along with a board restructuring and the CEO’s appointment to a presidential advisory council.

In early March, the company announced a conference call for March 17 (U.S. time) to release its full-year 2025 financial results and business strategy, boosting expectations for its future roadmap. (oklo.com)

Founded in 2013 and based in Santa Clara, California, Oklo develops advanced nuclear technology. Its business model centers on the Aurora Powerhouse, a small fast reactor designed to deliver 15–75 MW of electricity to data centers, remote communities, and industrial sites. (Wikipedia)

OpenAI co-founder Sam Altman once served as its board chair. After merging with a SPAC in 2024, Oklo listed on the NYSE and has since emerged as a leading next-generation nuclear growth stock, driven by rising AI power demand and renewed U.S. nuclear-energy policy support. (Wikipedia)
